An incoming x-ray with a wavelength of 1.55 X 10^-11 m undergoes
Compton scattering causing an electron to recoil with a speed of
1.35 X 10^6 m/s.
a) Determine the energy of the incoming x-ray (in keV)?
b) Determine the change in the x-ray wavelength after
scattering.

c) Determine the angle that the x-ray was scattered.

d) Determine the energy of the x-ray after scattering.
